Escape the underground corridors to make your way up to the exit level. This puzzle involves mostly tractor beams and some portal fling. You might find getting the first cube in the first main chamber a bit of a challenge. The timing is slightly tight, but not too strict.

Somehow the "Corridor" part of the name had me half expecting lots of long, poorly lit passages with very little direction (not a stab at your mapping, just PeTI conditioning!). But I really like the little locked off sections. You've got a talent for taking a ooncept and applying it pretty consistently across a map. Not super hard, but fun. Cheers

Thanks. I'm glad you like it. I actually was thinking about dimly lit corridors with light from the other sections shining light into the corridor. Such as very well lit rooms shining light into the hallway. But it seems to take an immense amount of lighting to get that affect. So I decided on "some" lighting in the hallways.

"some" lighting is all it takes

This map was frustrating difficult. You need to time REALLY well to complete the puzzle. The map name was a little misleading, I thought it was underground.
At some time, I feel like giving up because it was just too frustrating difficult, by well, I still solved it! Anyway, my blindrun is 27 mins long, I hope you won't find that painful to watch! >_< (Hopefully it'll be useful, it took 3 hours to upload it!)
Here's my blindrun: (Sorry if I stopped sometimes during the video, I was either thinking or texting my friend. xP)

The first chamber was difficult, it requires you to time really well, but it was indeed a creative and good puzzle. I didn't use the 90 degree panel though. Overall, I took 18 mins to complete it.
The second chamber was kinda easy. I only took 2 mins to complete it.
The third chamber was hard, but creative. I took ~ 7 mins to complete it.
I think you need to seperate your chambers, so players don't need to think whether should they bring the cube from the previous chamber or not. Like in the first to second chamber, there was a panel. At least close the panel so that the player can't go back? And the second to third chamber, it was just seperated by an Emancipation Grill (fizzler), it makes me think whether should I or should I not bring the cube over to the third chamber.
Good job on the puzzles though, it seems that you're really capable of creating awesome (and frustrating) puzzles.
5/5 from me, Keep it up!

Thanks for playing. I'm glad you liked it (as frustrating as it may be). LOL. Yes, the title can be a bit misleading about being underground because there's only so much that can be done with the PTI Editor. I was trying to keep the lighting at minimum through chambers 1, 2, and 3 as well as the same level till reaching the last chamber which was higher up and brightly lit. I guess if I used Hammer, I could make the lower levels look filthy dirty to give it the correct nuance. One of these days I'll sit down and try to learn it. As for 27 minutes long, wow that was a wee bit of gameplay. Actually we'll call it an even 20 minutes when we exclude the http social contact . Which BTW was probably in chamber 3 as you let the cubes get fizzled one after another. We know Glados has a whole warehouse full of them .

As for the parts where the player might wonder whether to bring the cube with them or not, yes, it can lead to the puzzle being counter-intuitive. I'm going under the assumption that the player will see that the forthcoming emancipation grill is "fixed" and can not be de-activated because there are no indicator lines adjoined to it. However, with existing indicator lines in close proximity, I'm assuming there's a chance of visual clutter and the player might not see that the grill is permanent. I will keep this in mind in the future (unless the layout can clearly indicate "the cube stops here" type of intuition).

As for the length of the video, no, it wasn't all that painful to watch considering the length. I think I was feeling your pain on the first chamber more than anything. Almost as if you're saying "I'm going to get that damn cube if it kills me." As always, I appreciate others taking the time to record their gameplay and upload it. I know what uploading time can be like considering I only have .5 Mbps up speed.

Thanks for sharing. Much appreciated.
Cheers.

Hahahaha!! Yepp, indeed it was in the third chamber, when I was standing on the funnel button and was fizzling cubes over and over again. ^^ It wasn't that long, right? More like only 30 seconds instead of 7 mins. xP

Yeah, I noticed that the grill is permenant, as no indicator lights are linked to it but the chambers are really close. Perhaps make a hallway?

Hahahahaha, thanks!!! Yeah, Glad you felt my pain.
No problem, cheers!
